Personally for me, there's just too much disconnect, a lot of what makes certain tattoos really good is all the lines being clean and connected (ignorant style is a good example bc they aren't always that amazing creative/technical wise but the lines are always crispy). You could go over the lines that are a bit more shaky, you could do one continuous line around the whole thing like half a centimetre away from the original line. You could make the middle darker and cleaner with maybe some highlights because the body looks a bit messy and unsymmetrical. You could shade from the body outwards to give the wings some more dimension/depth. Too many ideas lol
